I am new to this but very excited to learn. I just bought a 75 gallon freshwater tank. Gravel substrate, plastic planted. Using Penn plax silent air x5 air pump, cascade 700 canister filter. Using 2 bubble wands running the length of tank in the back. Waterfall bar on top of tank. My issue is that within an hour or so of adding my fish the water turned cloudy. I have not bothered or added anything product to the tank. I was wondering if it is the bacteria bloom that I have read about. Today is only day three of the initial cycle. My fish appear to be fine so far. Any input would be appreciated. Thanks!
